10 Claims.

My invention relates to the art of ornamenting material for use in making articles of wearing apparel.

The object of my invention is to provide a inachinefor making pinlred piping by the use of a vstain or plastic applied to the margin of a sheet of material such as leather, that will be aclose imitation of the pinked piping as heretofore made by the use of a separate strip of material attached to the sheet.

A further object is to provide an imitation pinked piping by applying to the margin of a sheet of material a band or color and notching said hand and sheet to provide a serrated edge which ysimulates a pinlred piping.

A further object of my invention is to provide a new process for ornamenting the marginal portions or portion of a sheet of material such as leather, by the use of a paint or stain and simultaneously cutting thru the sheet and painted portion by the use of a serrated wheel which forms an uneven edge and provides an imitation pinked piping.

Referring to the drawing which forms a part of this application:

Fig. l is an elevational view of a machine, shown partly in section, used in making said imitation pinlred piping.

Fig. 2 indicates a fragmental portion of a Wheel ffl having a serrated periphery which cuts thru the material to make an edge portion thereof to provide a pinlied edge.

AFig. 3 is a plan view of a portion of the Wheel shown in Fig. 2 showing the form of the cutting edge of the wheel.

Fig. 4 is a side veW oi the imprinting wheel,

shown on an enlarged scale.

Fig, 5 is a plan View of a portion of the imprinting wheel having a serrate or roughened tread o surface, and having a side portion adjacent thereto which is formed to provide a toothed gear.

Fig. 6 is a plan view of a portion of a sheet of material such as leather, illustrating the pinked piping as it appears when made in successive op- 111'3 erations.

Fig. 7 is a plan view of the sheet illustrative of the appearance of the margin as it appears when complete in a single operation which consists of applying the band of paint tothe margin i?) of the sheet and simultaneously forming the pinked odge in the act of cutting thru the sheet.

In carrying my invention into practice, I prefer to complete the work in one operation where the width of the stripe portion thereof is prede- 53 termined, but in the case Where the width of the (C1. til-11i) of the uniform thickness of the sheet as a Whole. p

The imitation pinned piping comprising an edge portion of sheet material that is uneven in form', and is provided by applying a stripe of paint or stain of predetermined width in the form of a hand to the surface of the sheet and simultaneously or successively dividing the sheet by the use of a serrated wheel which cuts thru the striped portion and provides an edge which imitates a pinked piping of the usual construction.

The Width of the band portion depends upon the depth and width of the notches formed in the material, and the color may he such as to har'- monize with the color of the sheet, or of any color other than that of the material. to which it is applied, and in some cases may be of the same color but of a diiferent tint or effect.

Referring to the machine used in making the herein described product,

lil indicates a table the top of which is made of smooth metal.

i I indicates a frame mounted on the table and having an arm i2 which extends over the table a predetermined distance therefrom.

yi3 indicates a shaft which may be rotated in any desired manner, and a Wheel i@ is mounted thereon and driven thereby.

The periphery of the wheel it rests in Contact with the top oi the table it, and is hereinafter referred to as the cutting Wheel.

The cutting wheel it is formed to provide a serrated or notched outer rim portion it which serves to cut thru and divide the sheet i5 in forming the serrated edge of the sheet, said notched portions'extending from the outer edge of the Wheel toward the axis thereof and serving as gear teeth to mesh with and drive the adjacent Wheel 23 Which'is provided with corresponding teeth.

The upper portion of the frame l2 carries a lever it Which is hinged to the frame at Il and carries an arm it in hinged relation at is, both lever and arm having an upturned portion at its free end connected together by a spring 2t which serves to pull said end portions toward each other and thereby cause engagement of the adjacent wheels.

Carried by the arm I8 is a two-part housing 2I formed to provide a circular chamber 22 having parallel side walls between which is closely mounted a wheel 23 which extends below the casing or housing and is carried in inclined relation to the wheel I4, and has serrations or teeth 24' corresponding to those formed. in the side of the wheel I4 and tted to mesh loosely therewith and permit a certain amount of upward movement of the housing and wheel 23 relative to the wheel I4 while the gears are in mesh and the wheels are rotating in unison.

The outer periphery of the imprinting wheel 23 extends laterally a distance from the serrations in its sides to provide an unbroken tread portion 24 which is spaced from the table top a distance corresponding to the thickness of the material I5 and the tread portion is roughened and serves to carry the paint and press it upon the sheet in the form of a band, and also serves to grip the surface of the sheet and aid in moving it in the act of cutting it and forming the pinking.

The housing is formed with a conduit ZI on the upper end of which is carried a cap 25 which supports the paint receptacle 26 The paint or stain is very fluid and flows freely from said receptacle thru the conduit to the top of the wheel 23 and is carried thereby in the serrations 24 to the work as the wheel is rotated, the paint being forced against the cutting edges of the wheel I4 and laterally under the tread surface 24 of the wheel 23, as will be readily understood.

A spring 2l' connected to the frame I I and lever I6, is under tension and serves to hold the wheels I4 and 23 constantly in mesh regardless of the thickness of the sheet I5, the thickness of the sheet serving to automatically position the wheel 23 relative to the wheel I4.

The housing is easily detachable from the lever I6 for the purpose of cleaning or for changing for another housing having a wheel provided with a different width of treat surface, and also is free to be swung outward from the wheel I4 for cleaning or inspection.

28 indicates the strip portion removed from the sheet in the cutting operation.

In Fig. 6 the band of paint is made wider for the purpose of forming a colored portion on both the sheet I5 and strip 28 cut therefrom in the process where the pinking is done in a subsequent step, this method serving to provide a separate strip having a pinked edge that is colored, and which may be used as an ornamental trimming, and if the strip portion is of sufficient width, to provide two sheets of finished material.

When the sheet is finished by a simultaneously operation in which the paint is applied at the same time that the sheet is cut thru and the pinking operation is performed, the paint is applied at one side only of the cutting wheel by the imprinting wheel, leaving the strip portion practically free from paint.

In operating the machine I prefer to use a small motor to rotate the shaft.

The rotation of the shaft drives the meshed wheels in unison and the sheet is fed under them and automatically advanced as the paint 29 is applied by the imprinting wheel and the sheet divided in the act of forming the pinked edges in the sheet and strip, or in both sheets when the process is carried out in two operations as hereinbefore described.

If desired, a line of stitching 30 may be applied adjacent the edge of the stripe, or such a line may be imprinted by the imprinting wheel to simulate a stitching, and thus further simulate a pinked piping as heretofore made.
